P0341 on a Toyota: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can usually drive, but if the engine runs rough or stalls, stop and have the timing checked — a jumped timing chain can cause major damage.

What P0341 means on a Toyota

On a Toyota, P0341 means the camshaft position sensor on bank 1 is sending a signal that is out of the expected range. The computer uses this sensor to time fuel injection and ignition, and the code can point to a failing sensor or, more seriously, a stretched timing chain or VVT issue.

Is P0341 common on Toyotas?

P0341 shows up on Toyotas with higher mileage, especially Camry, Corolla, and RAV4 models with VVT-i engines. A failing camshaft sensor is the common cause, but on high-mileage engines a stretched timing chain can also trigger the code, so it deserves a proper diagnosis.

Commonly reported on: Camry, Corolla, RAV4, Tacoma.

Symptoms

Check engine light on
Hard starting or no start
Rough idle
Reduced fuel economy

Common causes

most common: Failing camshaft position sensor
common: Stretched or jumped timing chain
common: Damaged wiring or connector at the sensor
less common: VVT actuator or oil pressure issue

How to fix it

Fix	DIY?	Typical cost
Replace the camshaft position sensor	Yes	$80–250
Repair sensor wiring or connector	Mechanic	$100–300
Replace a stretched timing chain	Mechanic	$900–1800

Frequently asked questions

Can I drive a Toyota with a P0341 code?

Usually yes, but pay attention to how it runs. If the engine stalls or runs very rough, stop driving and have the timing checked, because a jumped chain can cause major damage.

What usually causes P0341 on a Toyota?

Most often a failing camshaft position sensor on higher-mileage Camry, Corolla, and RAV4 models. On older engines a stretched timing chain can also set the code.

How much does it cost to fix P0341 on a Toyota?

Replacing the camshaft sensor typically runs $80–250 with parts and labor. If the timing chain is stretched, expect $900–1800 for the repair.
